DESCRIPTION
A mild steel wire mesh reinforced, high quality asbestos free material which complies with the test requirements for BS7531 Grade X. Composed of aramid/inorganic fibres, bonded with Nitrile elastomer. The formulation gives the material good chemical stability and an excellent resistance to creep at high temperature. This material has a fine, mild steel mesh reinforcement and is graphited.SERVICE
High temperature applications. It is suitable for: gases, oils, solvents and high pressure steam, most dilute acids and alkalis and oxygen. The mild steel wire reinforcement is particularly suitable for absorbing vibration and applications requiring a higher load bearing capacity.Max recommended temperature : SHORT TERM 450°C
Max recommended temperature : OPERATING 350°C
Max recommended temperature : OPERATING STEAM 220°C *
Max recommended pressure : 16.4MPa / 166 BAR
These temperature and pressure guides cannot necessarily be used simultaneously and may not apply to all thicknesses. The operating temperature for non-asbestos sheet materials is related to the thickness of the material. Thinner materials offer better temperature and pressure properties.
